Allergen
in negative feedback. when an enzyme (negative feed back mechanism) produces too much of a molecule or substance that substance binds to the enzymes allosteric site to hault production of that substance (negative feedback response). and the whole process is the negative feedback loop.
This is a pH indicator.
The hormone that primarily regulates the fight-or-flight response is adrenaline, also known as epinephrine. Released by the adrenal glands during stressful situations, adrenaline triggers various physiological changes, such as increased heart rate, heightened alertness, and redirected blood flow to muscles, preparing the body for immediate action. This response is part of the broader activation of the sympathetic nervous system.
The fight or flight response is primarily regulated by the hormone adrenaline (also known as epinephrine), which is released by the adrenal glands in response to stress. This hormone prepares the body to react quickly to perceived threats by increasing heart rate, dilating airways, and redirecting blood flow to essential muscles. Additionally, cortisol, another hormone released during stress, helps sustain the body's response over a longer period. Together, these substances coordinate the physiological changes necessary for survival in dangerous situations.
